To all whom, it may concern:

Be it known that we, FRANCIS PAUL. J r., and ALBERT FREDERICK GUNDLACK, of the city of Sorel, Province of Quebec, Dominionof Canada, have invented certain new and useful Improvements in Carburetors; and wedo hereby declare that the following is a full,

clear, and exact description of the same.

Our invention relates particularly to the to generation of a burning gassuitable for illuminating and healing; and ithas for its object to produce gas more economically and a gas varying in density according to requirements.

4 IS The invention may be said briefly to consist in causing air in variable'quant-ity to pass through a variable proportion of a liquid bydrocarbon or a substance containing hydro carbon in a state having an afflnity for air. To this end we supply air or any other gas to be enrichedto the lower end of a carbureter charged at its lower end with a substance adapted to impregnate said air or other gas with volatilized hydrocarbons when. it passes therethrough, which it is caused to do by being fed under a slight pressuret o said substance, (usually in liquid form,) at Variable distances below the surface thereof, and al'-- flec'ted from said supply and caused to mix.

with the carburized air orother gas before it flows to its point of consumption. i More specifically speaking, our invention consistsin furnishinga carbureter with means for feeding preferably dryair or other gas into a subchamber or carburizing-chamber proper within the carbnreter and flooded with a liquid hydrocarbon, from which it is allowed to slowly find its way to the gas-storage portion of the carbureter. A branch from said air or other gas supply leads to a perforated hollow annulus, from which said air or other gas flows in minute bubbles to the interior of said carburizin'g-chamber proper through the carburizin'g 'su bstance and thence to the storage portion of the carburetor, this branch being preferably under control of a valve to regulate theproportion caused to be deflected to be carburized more thoroughly.

Our improved apparatusis caused to run without attention for a considerable time by providing an independent'supply of the car-. 'burizing substance and adapting a means controlling said independent supply to automatically cause same to. flow into the car- :bureter and replace the carburizing substance depleted during the operation of the plant.

For full comprehension, however, .of our.

invention reference must be had to the ac.-

companying drawings, forming apart of this specification, in which like symbols indicate the same parts, and ,wherein 1 Figure l is a longitudinal vertical section, partly in side elevation. Fig. 2 is an enlarged longitudinalvertical sectionalview of'our im-. proved carbureter removed from its tank,

taken on lineAB, Fig. 3. v thereof. Fig. lis a plan View of our improved 7o Fig. 3 is a plan view collapsible tank, and Fig. 5 is a side elevation of the clockwork for driving the blower.

Our improved carburetor proper comprises a tank I), beneath which a pipe extends hori-' zontally, as atf, and has its end bent to pro- 1 V jectvertically, as at g, into the center ofthe interior of said tank, while an air-conducting pipe h leads .from a branch 72, from the air-supply tank 0 and is connected to the outer end of said pipe'f. A tubular capt' fits loosely over the vertical portion g of-the airconducting pipe and is carried by a float, consisting of a hermetically-sealed box j, oncircling the said cap, adjacent to the lower end thereof, and provided with a perforated flared depending plate k, of umbrella'form,

the peripheral edge whereof is sufficiently less in length than the interior measurement of the tankto allow of an easy vertical move ment of the float. The carburizing substance 0 we prefer to use is any hydrocarbonaceous oil, with which We charge the supply-tank d end bifurcated to straddle the tubular cap, to which it is pivotally connected, as at 1), while its other end is connected by a link q to valve-stem 'r. This connection has the effect of automatically causing the valve m to be opened when the oil in the carbureter, and with it the float, sinks below the required level, thereby replenishing said carbureter and automatically shutting off the supply when the required level has been again attained. pipe 5, for which purpose a branch 25 extends laterally therefrom and is furnished with a flared mouth u,norm ally held closed by a valve v, seated therein and connected to a lever 10, fulcrumed atoneendtoabracketmandhaving the portion thereof adjacent to the other end grad uated,with a counterpoise slidable thereon, which is moved'toward or from the end of said graduated portion to allow said valve to open and exhaust the space above the oil in the supply-tank when the pressure in said space exceeds any given point. The upper end of this vertical pipe has an elongated is supported upon a block 4, floating on the surface of the oil in the supply-tank, the function of this rod being to indicate in conjunction with the graduations of said glass tube the depth of oil in said supply-tank. The carbureted gas is drawn from the carburetor through a pipe 6 and taken therefrom through any suitable pipes (not shown) to the point of consumption, while a safety blow-01f is provided for said carbureter by connecting said pipe 6 by a branch pipe 7 to the blow-off pipe S.

In orderto enrich the gas being producedas may be necessary, for instance, if a poorer grade of oil is being used-we provide means for causing a portion of the air being supplied to be subjected to a greater proportion of oil, and therefore absorb more hydrocarbon. To this end a pair of branch pipes 8, arranged in the form of a V, are connected at their apex to the valve-chamber 9 of a plug-valve 10, having a squared top 11, the valve-chamber also communicating with the interior of the cap 2' and the valve 10 being operated from outside of the tank by'a rod 6. The lower ends of these branch pipes project downwardly through the floatj and umbrella-section 7c and are connected with and carry a perforated hollow annular distributer 12, located ashort distance below the lower end of the cap 2'. To reduce the density of the gas being supplied from the carbureter, we cause air to be mixed therewith in the following manner: A branch pipe 14 is taken from the air-supply pipe through the wall of the carbureter at a point above the highest level of the oil therein. A valve 15 controls The supply-tank is filled through a this branch pipe by the opening of valve 15 to be discharged into the gas-chamber of the carburetor in spray form, thereby increasing the proportion of oxygen to the carbon absorbed from the oil and rendering the gas more easily burned and of greater volume.

Our improved air-tank consists, preferably, of a jacket 20, of material impervious to air, stayed by a series of hoops 21 and a solid top 22, which carries a series of perforated arms 23, the perforations whereof take loosely over and slide upon a series of vertical guide-rods 24, mounted rigidly in a frame 25, while a weight 26 is carried upon the top of this collapsible tank, which is charged through a port 27.

The operation of our improved plant is as follows: The air-tank is first charged with air by opening the air-intake valve 27, raising said tank to its full height, and then closing said air-intake valve. The air is then caused by the pressure of weight 26 to flow through pipe 71, f, and g and between cape and the vertical portion 9 of the supply-pipe to the under side of the umbrella-section k, which is, as shown, flooded with the oil through the perforation in said umbrella-section andrthe body of oil above the level thereof to the upper portion of the carbureter, where it is held in a carburized state until drawn therefrom for use. If it is found that the gas is too rich and that it can be economized while yet supplying the demand for consumption, atomized air is mixed with the gas, as hereinbefore described, while to enrich the gasa portion of the air is defluted from the supply thereof first described and caused to be subjected to a greater quantity of the oil' by en-' tering same at a'lower level.

with, in which case with the constantly open communication between the supply-tank and the carbureter the levels in both will equalize, and as the oil in the carburetor is consnmed it will be of course to a reduced extent replaced with fresh oil from the oiltank; or, furthermore, if desired the oil can be fed at intervals direct to the carburetor and the supply-tank be dispensed with.

Our improved air-supplying mechanism is automatically actuated as follows: A blower is actuated by a clockwork mechanism (indicated at 51) adapted to be Wound up by a crank-actuated drum 52, this blower being connected by a pipe 53 to the beforementioned branchh, and the point of communication thereof with said branch h is controlled by a one-way valve 54, while the point of communication between said branch 7L and the collapsible tank is controlled bya one-way valve 55. The point at which the branch air-pipe 14E is connected to this branch h is intermediate the said points of communication between the branch h and the pipe 53 and the collapsible air-tank, respectively; "The operation of this air-supplying device is as follows: The drum having been wound, it will impart through the clockwork mechanism 51 a rotary motion to the blower 50, with the result that air will be forced valve 55 and close 54, thus continuing they supply until the clockwork mechanism can be again wound up.
